Is aws s3-like "cloud storage" supported?

[celesteking]

I don't understand whether s3 based cloud storage is supported or not. Internet is giving me differing opinions.

I get it that I can mount an s3 service via s3fs, but from my experience it's awfully slow to the point of no use for anything production-grade.

Thanks.

borg 1.4.x is the current stable release for production. It does not have any cloud support builtin. Some people use it with rclone or other cloud tools though.

borg master branch (future "borg2") is in beta and not production ready yet. It has cloud support via borgstore.

To make that concrete: borg 2 (master branch, currently beta) talks to S3 and S3-compatible object storage natively via borgstore's S3 backend - no s3fs / FUSE mount involved, so you are not paying the price you describe.

Repository URL syntax:

(s3|b2):[(profile|(access_key_id:access_key_secret))@][scheme://hostname[:port]]/bucket/path

For AWS S3 the scheme://hostname[:port] part can be omitted; bucket and path are always required. For other S3-compatible providers, point hostname (and port, if needed) at their endpoint. Credentials come either from a boto3 profile or inline in the URL - see the boto3 docs for the credential options.

The backend needs its optional dependency: pip install borgstore[s3] (boto3).

Note: with some S3-compatible services, e.g. Backblaze B2, s3: is known to cause trouble - use b2: in the URL instead.

borg 1.4.x (current stable) has no built-in cloud support, as mentioned above.

Closing as answered - please open a new discussion if you run into problems with a specific S3 provider.
